A few more data points on this. I consistently get this oops on our new Dell PowerEdge M600, but do not get the oops on a Dell PowerEdge 1955. They are the same model card, but slightly different revisions: Dell M600: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08) Dell 1955: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS (rev 01)
I applied the upstream patch to the 2.6.24-12 sources and re-compiled the module. The patch location was slightly different, but it patched and compiled cleanly. I then swapped in this patched module after the "Loading Additional Components" step, but before the "Configuring the Clock." With the patched module, the installer is able to load the module and the installation proceeds normally. Of course, the unpatched module gets installed in /target, so I have to swap it in there before the reboot so that the machine does not panic at boot. :-) I'm not sure what the next steps are to help the kernel team get this patched, but I'm happy to provide any additional information and/or assistance. If this could make it into hardy final, we'd love to see this, since we're trying to move our servers to the LTS release. I've attached the actual patch I used on the hardy linux 2.6.24-12 sources this morning. ** Attachment added: "mptsas.patch" http://launchpadlibrarian.net/12858228/mptsas.patch -- Kernel Oops - unable to handle kernel NULL pointer dereference; EIP is at mptsas_probe_expander_phys+0x72/0x610 [mptsas] https://bugs.launchpad.net/bugs/205162 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
